Cornelius Jonathan Cornelius is a forester with special interests in smallholder (agro)forestry and tree domestication. He has worked principally in Latin America (most recently as leader of ICRAF‘s work in Peru) and the Pacific. He currently leads James Cook University‘s Agroforestry and Novel Crops Unit (Queensland, Australia), where he is involved with agroforestry and tree domestication projects in Papua New Guinea and Far North Queensland. 3 Summary Background 1. The World Agroforestry Centre (ICRAF) has been active in the Peruvian Amazon since 1991. In spite of changes in emphasis, organizational structure, and its collaborative arrangements, the broad focus of its work during this time has remained constant, i.e. the generation (through biophysical research) and facilitation (through biophysical and social science research and training) of means of preventing, mitigating, or reversing resource degradation. 2. The Amazon region makes up around 60% of Peru‘s terrestrial area. Much of the Amazonian population of around 3.85 million lives in poverty or extreme poverty. This situation is associated with a process of land degradation linked to increasingly short fallow periods, illegal coca cultivation, and conversion of forest to unproductive grasslands. The original forest cover has been lost from about 90,000 km2. Of this area, 55,000 km2 are considered to be degraded or abandoned. Degradation processes are most advanced in terms of magnitude and intensity in the Selva Alta (rainforest in the altitudinal belt 400- 2600 m a.s.l.). 3. Although ICRAF‘s work has targeted resource-poor farmers, the underlying justification, implicit or explicit, of this work has been environmental: to slow or halt deforestation and associated environmental degradation. For this reason, ICRAF research in Peru has focused on the Amazon rather than the principal concentrations of extreme poverty and tree scarcity (i.e. parts of the Andes). 4. Until 2003, a broad programme of research was conducted, i.e. across ICRAF‘s research programmes. Subsequently, due to increasingly scarce funds, research concentrated almost exclusively on continuation of the Tree Domestication Project (TDP) begun in 1995. 5. From 2003, as a response to diminishing funding, ICRAF also led the development of the Amazon Initiative Consortium. This process led to the approval in 2007 by the Consultative Group on International Agricultural Research (CGIAR) Science Council of the Amazon Initiative Eco-regional Program (AI-EP). 6. With the approval of the AI-EP and its associated thematic agenda, and due to the advanced state of the TDP, and also taking account of the new CGIAR structure and the ―MegaProgams‖ associated with it, ICRAF-Amazon decided to review its tree domestication activities in Peru. Accordingly, the present report, based partly on field visits and interviews in Peru in July 2009, was commissioned. Status quo ante relevant to the future of the TDP: AI-EP and ICRAF-global agendas 7. The AI-EP‘s four ―innovation foci‖ can be distilled to three essential components: identification of profitable products (tangible goods, environmental services, etc.); development of sustainable production systems for these products; creation of a favourable policy environment, potentially both in terms of removing constraints and of instituting positive innovations. Overall, the AI-EP agenda appears similar to the agenda that ICRAF and partners have pursued in the Peruvian Amazon since 1991, but with different institutional arrangements. 4 8. ICRAF‘s Global Research Program 1 (Domestication, utilization and conservation of superior agroforestry germplasm) has two research outputs: ―improved agroforestry tree germplasm available with associated information on potential use, benefits and conservation while considering climatic constraints and risks of invasiveness‖ (GRP 1.1); ―prototypes available for sustainable tree seed and seedling supply systems that promote the use of diverse and productive germplasm by smallholder farmers in different social, economic and cultural settings‖ (GRP 1.2). ICRAF considers one or both of these outputs to be relevant to six of the eight CGIAR MPs: MP1 (Agricultural systems for the poor); MP2 (Enabling agricultural incomes for the poor); MP4 (Agriculture, nutrition, and health); MP6 (Forests and trees); MP7 (Climate change); MP8 (Agricultural biodiversity). Status quo ante relevant to the future of the TDP: agroforestry practice and research in the Peruvian Amazon 9. Traditional agroforestry is practised commonly in the Peruvian Amazon, particularly by indigenous and ribereños (long-established mestizo and deculturated indigenous farmers of riverside lands). By contrast, tree planting or nurturing on a large scale by colonist farmers seems to be less usual. 10. Fruit trees are the species most likely to be planted by small farmers. Trees are also highly valued for timber, fuelwood, and construction, but are rarely planted for these purposes because of their high abundance in secondary and primary forests. 11. Illicit coca is one of the most important perennial crops in the Peruvian Amazon, particularly in the Selva Alta. This is due to factors that outweigh the disadvantages of illegality: (a) relatively high, relatively stable prices; (b) ready markets; (c) key agronomic advantages; (d) ease of processing, value-adding, and transport; (e) the real or perceived lack of alternative livelihood options. 12. ―Project agroforestry‖ (agroforestry promoted by development projects, typically consisting of practices novel to the target farmers) has been promoted by various development agencies, particularly in Selva Alta, but to date there have been few independently documented cases of clear livelihood benefits or widespread adoption. 13. By contrast, one form of traditional or semi-traditional agroforestry, cacao or coffee agroforestry with shade trees, is well established and associated with important export crops and important livelihood contributions. 14. Other more recently introduced or developed perennial crops, usually cultivated in monoculture, have also been associated with significant positive impacts on livelihoods, e.g. oil palm, camu-camu (Myrciaria dubia). 15. There is no reason in principle why species that conventionally are profitably cultivated as monocultures should not contribute to the positive economic, environmental or social impacts of ―agroforestry landscapes‖. 16. Smallholder farmers, with the exception of relatively prosperous landowners in the Selva Central (a zone located within 5-6 hours road access of Lima), have not adopted to any notable extent the plantation-based production of either fast-growing or high-value timber. 17. ICRAF studies have shown that in traditional agroforestry, the main sources of germplasm for farmers tend to be their on-farm trees, neighbours, fruit markets, and local remnant high forests. Farmers‘ germplasm sourcing practices for fruit and timber trees are different: the former tend 5 to be planted from seed, often with conscious selection, whereas seedlings for timber trees tend to be sourced as wildlings in neighbouring forest or crop fields. Physical shortage of germplasm is said not to be a constraint on traditional agroforestry practices. 18. Traditional germplasm supply systems are inadequate to supply the germplasm needs of development projects. In Peru there is no formal germplasm supply system for timber trees, so NGOs and other agencies are likely to experience difficulties in germplasm sourcing. For many native timber species of interest, and for exotics of interest, such as teak, there are no recognized seed sources. The situation in fruit species parallels that of timber trees. Although, for a few species, either traditional or breeders‘ varieties are available, for the majority of species of possible interest there are no improved sources or cultivars available. 19. Agroforestry research in the Peruvian Amazon can be classified in two categories that sometimes overlap: research published

E-mail: Abstract: The Rondônia Natural Resources Management Project (PLANAFLORO) was a strategic program developed in partnership between the Brazilian Government and The World Bank in 1992, with the purpose of stimulating the sustainable development and protection of the Amazon in the state of Rondônia. More than a decade after the PLANAFORO program concluded, the aim of the present work is to recover and share the information from the long-abandoned plant collections made during the project’s ecological-economic zoning phase. Most of the material analyzed was sterile, but the fertile voucher specimens recovered are listed here. The material examined represents 378 species in 234 genera and 76 families of angiosperms. Some 8 genera, 68 species, 3 subspecies and 1 variety are new records for Rondônia State. It is our intention that this information will stimulate future studies and contribute to a better understanding and more effective conservation of the plant diversity in the southwestern Amazon of Brazil. Introduction The PLANAFLORO Project funded botanical expeditions In early 1990, Brazilian Amazon was facing remarkably in different areas of the state to inventory arboreal plants high rates of forest conversion (Laurance et al.

  • Eco-Practice Stories Shared by Wiproites(PDF)
    A compilation of stand-out eco practices from the world over shared by Wiproites. A part of Wipro's Sustainability Report 2008-09 Preamble This compilation of twenty eight eco practices is a contribution by Wiproites. They are some fine examples of green practices from across the world, carefully handpicked from a large number of entries. These stories have been so chosen because they stand-out in our trying times - they inspire us, they trouble us, but importantly, telling us what more can be and should be done. They tell people about the hard work and efforts put in by communities and countries to bring about eco awareness and in some cases a more conscious way of living. These practices have been brought to life especially for this report by some very real and soul- searching illustrations by Wiproites and a few amateur student artists from some of Bengaluru’s finest art institutions. For an easy understanding of the stories we have categorized them into the following five sections. These sections all meet to form a common mosaic but different elements shine in the forefront of each: Communities at the forefront; Conservation at its best; Green innovation; Sustainable agriculture and Sustainable cities. Communities at the forefront. This section comprises inspiring stories of individuals or communities that have always put the environment before themselves; bringing about a sea change in the attitudes and mindsets of people and helping them live a better life. Seldom will you come across a community that so strongly believes in living Her young daughters were not daunted and offered their heads too.

Abstract— In the present study, mulateiro (Calycophyllum spruceanum) stem cell (MSC) extract was evaluated for its antioxidant activity and anti-senescence effect against hydrogen peroxide (H2O2)-induced oxidative stress in human adult fibroblast (HAF). Mulateiro is used as a medicinal plant for the treatment of skin wounds, cuts, burns and is also known to help combat the skin aging effects, parasites and fungal infections. Cells were treated with MSC extract following the induction of H2O2 oxidative stress. The senescence associated β- galactosidase (SA-β-gal) activity was used to evaluate the Anti-aging effect. MSC extract demonstrated antioxidant activity and anti- senescence effect against oxidative damage in fibroblast cells and suppressed H2 O2 stress-induced premature senescence in a concentration-dependent manner. At 0, 01 (0,1%) and 0,05 mg/mL (0,5%), MSC extract showed a positive effect by minimising cell cycle arrest and apoptosis induced by hydrogen peroxide. These findings provide scientific support for the potential use of mulateiro stem cell extract in treatment of skin disorders and as a skin anti-aging agent.

    AGRICULTURA TROPICA ET SUBTROPICA VOL. 44 (4) 2011 Original Research Paper MORPHOLOGICAL AND GENETIC DIVERSITY OF Calycophyllum spruceanum (BENTH) K. SCHUM (Rubiaceae) IN PERUVIAN AMAZON TAUCHEN J.*, LOJKA B., HLÁSNÁ-ČEPKOVÁ P., SVOBODOVÁ E., DVOŘÁKOVÁ Z., ROLLO A. Department of Crop Sciences and Agroforestry, Institute of Tropics and Subtropics, Czech University of Life Sciences Prague, Czech Republic Abstract Calycophyllum spruceanum is an important timber tree species in Peruvian Amazon Basin. Diversity was observed with reference to both morphological traits and genetic variance. Variance analysis showed significant differences in locality (site of collection) (p < 0.05). Provenance and progenies showed lower variation than locality. Genetic diversity was assessed using two Internal Transcribed Spacer (ITS) primers ITS1 and ITS4. Fragment sizes ranged between 600 and 700 bp. UPGMA analysis separated provenances heterogeneously. The resulting similarity matrix revealed values ranging between 0.672 and 0.977, with an average of 0.823. PCA analysis was unable to separate provenances. Our results suggest that morphological diversity is higher than the genetic one. The discovered genetic diversity under introduced analyses proved the outcrossing reproduction cycle and population genetics of C. spruceanum. Cleary distinguishable characteristics for each provenance were not found. Environment factor had a higher impact on phenotype on these studied provenances and localities. Our results are in line with statements of previous studies on C. spruceanum, suggesting a higher variation within provenances than among provenances. Acquired data will be used for Inter Simple Sequence Repeat (ISSR) assessment, giving more precise view on genetic diversity of C. spruceanum in Peruvian Amazon. Keywords: Calycophyllum spruceanum; genetic variation; Internal Transcribed Spacer; morphological description, provenances.

  • Building Resilient Communities in Belize Through Climate-Smart Agricultural Practices
    Building resilient communities in Belize through climate-smart agricultural practices Gustavo Requena, Ya’axché Conservation Trust Christina Garcia, Ya’axché Conservation Trust Marvin Vasquez, Ya’axché Conservation Trust Corresponding author Gustavo Joel Requena Ya’axché Conservation Trust #20 George Price Street Punta Gorda Town, Toledo District Belize [email protected] Abstract Indigenous communities have always coexisted with nature. Their subsistence has had a dependence on the height- ened stewardship of the natural environment, requiring that their farming practices evolve and adapt to today’s rapidly changing environment. As the effects of climate change become more obvious in weather pattern alterations influencing agricultural yields, so do the resilient farming practices that are being adapted to strengthen the agricul- tural sector. Since forests are sources of livelihoods for Mayan communities, agricultural advances promoting forest conservation and good governance are viewed as socially and environmentally responsive approaches to rural devel- opment. Cacao-based agroforestry is a long-term solution to improve our forests’ health and livelihoods in southern Belize. This system allows for the development of entrepreneurship opportunities through small-scale business models in agrotourism that highlight the cultural and biodiversity richness in these communities. The incorpora- tion of apiculture and Inga alley cropping ensure that traditional crops such as corn, beans, and vegetables can be continuously cultivated, decreasing the deforestation rate, hence conserving our landscape and its ecosystem. These practices involve the growing of staples for the organized communities, who are embracing ecofriendly solutions for a sustainable future. The experience and knowledge developed within the communities have resulted in the devel- opment and application of climate-smart solutions and adaptation mechanisms that ensure livelihoods continue to thrive.

Hernández† Professor Centre de recherche sur le bois Département des sciences du bois et de la forêt Université Laval Québec (Quebec) Canada, GIK 7P4 (Received February 2007) ABSTRACT Calycophyllum spruceanum (Benth.) Hook. f. ex Shum. is an important timber species of the Peruvian Amazon Basin. Due to overexploitation in natural populations, users are turning to young trees of potentially lower quality. Therefore, variation in juvenile wood properties should be investigated to determine whether wood quality can be maintained or, if necessary, improved by breeding. A provenance/ progeny test was established to evaluate genetic variation in growth and wood properties of young trees, the strength of their genetic control, as well as their interrelationships both at the genetic and phenotypic ␴ levels. This paper presents results obtained for ultimate crushing strength ( L), the static compliance coefficient (s11) in longitudinal compression, the dynamic s11 in the longitudinal direction (determined by ultrasound), and air-dry density at 39 months. Results indicate that the mechanical properties of juvenile wood of this species are adequate for structural uses. There was significant variation in all wood properties due to families within provenances, and in all but dynamic s11 due to provenances. Families accounted for a larger percentage of the total phenotypic variance than provenances.

  • Andrew Berley North Lincoln High School Denver, NC Madagascar, Sustainable Agriculture
    Andrew Berley North Lincoln High School Denver, NC Madagascar, Sustainable Agriculture Madagascar: A Natural Solution to Soil Degradation and Slash-and-Burn Agriculture Madagascar is the world’s fourth largest island and is home to over 264,000 species of plants and animals. It is one of the only megadiverse countries that holds a majority of the world’s biodiversity with over seventy percent of the organisms on Madagascar found nowhere else in the world. (Smith, Rene) The climate is also diverse being tropical along the coast, temperate on the inland, and arid in the south. The land goes from being flat near the coast, to plateaus, and finally mountainous in the center. Due to Madagascar’s isolation from a mainland continent and its diverse climate and terrain, this is likely what caused the explosion of biodiversity in Madagascar. (Butler, Rhett) The modern nation of Madagascar began as a colony of France in 1895 where its main job was to supply France with raw resources. In 1960 Madagascar gained its independence and in 1993 it is now known as the Republic of Madagascar. There are two main heads of the Malagasy executive government. There is a president which is elected by the universal suffrage and a Prime Minister which is elected by Parliament. The president is the leader of foreign policy and the symbol for national unity. The Prime minister oversees the functioning of the government. (Butler, Rhett) The current population of Madagascar is twenty-four million people. Of the twenty-four million people forty-nine percent are employed and of that, seventy percent of the force works in agriculture.
